What's it like to be a single mom? As much as I never wanna be one I might..?

So I was thinking I have to have a baby... Immediately, so I have a bf he is long distance we can get pregnant when he comes here this summer and then I'll do my internship pregnant and have a baby and finish school. And if that doesn't work Idc as long as I am pregnant before 25 so what's single parenthood like??
